Antiperspirant and deodorant compositions

ABSTRACT

The present application relates to antiperspirant compositions comprising nitrogen-based and/or oxygen based perfume raw materials, and methods for making and using the antiperspirant compositions.

TECHNICAL FIELD

The present disclosure generally relates to antiperspirant and deodorantcompositions comprising perfumes and non-sulfur-based perfume rawmaterials, as well as methods for making and using such antiperspirantand deodorant compositions that resist consumer fragrance habituation.

BACKGROUND

Consumers desire antiperspirant and deodorant compositions that providea desired and long-lasting fragrance or scent each time the compositionis applied or used. Particularly in the case of deodorants, consumersmay also expect compositions that provide a scent that can mask oroverride other undesirable odors. While current antiperspirant anddeodorant compositions provide desirable scents, consumers becomehabituated to the perfume raw materials (PRMs) and perfumes utilized inthe existing compositions. As a result, for consumers to perceive thedesired scent consumers can use increasingly large amounts of theproduct to overcome the habituation or the consumer can to switch to adifferent product utilizing a different perfume for a significant periodof time to reverse the habituation. There is, therefore, a need forantiperspirant and deodorant compositions that provide long-lasting anddesirable scents that do not cause a habituation effect in consumers anddo not require consumers to modify their habits.

SUMMARY

In one example, an antiperspirant composition includes a perfume. Theperfume includes, based on total perfume weight, from about 0.000001% toabout 10%, of a perfume raw material. The perfume raw material includesone or more of a nitrogen atom or an oxygen atom, and not a sulfur atom.The perfume raw material resists the fragrance habituation of a consumerto the antiperspirant composition.

In one example, an antiperspirant composition includes a perfume. Theperfume includes, based on total perfume weight, a perfume raw material.The perfume raw material is selected from the group consisting of: (a)from about 0.00000005% to about 5%, of a perfume raw material comprisinga pyrazine moiety; (b) from about 0.00001% to about 20%, of a perfumeraw material comprising a nitrile moiety; (c) from about 0.000001% toabout 10%, of a perfume raw material comprising an indole moiety; (d)from about 0.00001% to about 10%, of a perfume raw material comprisingan oxime moiety; (e) from about 0.00001% to about 20%, of a perfume rawmaterial comprising an amine moiety; (0 from about 0.00000005% to about5%, of a perfume raw material comprising a diamine moiety; and (g)mixtures thereof. The perfume raw material resists the fragrancehabituation of a consumer to the antiperspirant composition.

II. PERFUMES

Antiperspirant compositions can include perfume materials. Manyconsumers prefer antiperspirant compositions that can consistentlyprovide a desired scent, or odor, that can be perceived each time theproduct is used. Perfume materials can provide the desired scent or odorto these antiperspirant compositions. These perfume (i.e., fragrance)materials can include perfumes, perfume raw materials, and perfumedelivery systems. Habituation of the perfume materials by the consumer,however, can lead to a diminished perception of the desired scent evenwhen the quantity of perfume material in the antiperspirant compositionremains consistent.

While not being bound by theory, it is believed that habituation is aphysiological phenomenon where the body is attempting to avoid havingits sense of smell from becoming overwhelmed by any one stimulus afterrepeated chronic exposure as part of a primal, darwanistic, defensemechanism. Applicants, therefore, theorizing that the source of thehabituation problem was evolutionary in nature, looked to odors that maybe associated with danger as Applicants believed that the evolutionarypath of those who became habituated to such odors would have been cutshort. Surprisingly, it was discovered that certain chemical moietiesthat are associated with conditions that may be detrimental to, orimportant in sustaining life, are not subject to the habituationphenomenon. Antiperspirant compositions can resist scent habitation byincorporating these chemical moieties as either perfume raw materials oras components in a perfume delivery system.

In one example, an antiperspirant or deodorant composition canincorporate a perfume that can resist scent habituation. The perfume canincorporate perfume raw materials that can resist the habituationeffect.

Antiperspirants compositions can also incorporate desirable scentsthrough inclusion of perfumes and perfume raw materials in perfumedelivery systems. Certain perfume delivery systems, methods of makingcertain perfume delivery systems, and the uses of such perfume deliverysystems are disclosed in U.S. Pre-Grant Publication No. 2007/0275866 A1.The perfumes and perfume raw materials previously disclosed can be usedin such perfume delivery systems. Such perfume delivery systems include:polymer-assisted delivery (PAD), molecule-assisted delivery (MAD),fiber-assisted deliver (FAD), amine-assisted delivery (AAD),cyclodextrin delivery system (CD), starch encapsulated accord (SEA),inorganic carrier delivery system (ZIC), and Pro-Perfume (PP). Examplesof these perfume delivery systems are further described below.

Polymer-Assisted Delivery (PAD)

This perfume delivery technology uses polymeric materials to deliverperfume materials. Classical coacervation, water soluble or partlysoluble to insoluble charged or neutral polymers, liquid crystals, hotmelts, hydrogels, perfumed plastics, microcapsules, nano- andmicro-latexes, polymeric film formers, and polymeric absorbents,polymeric adsorbents, etc. are some examples. PAD systems can include,but are not limited to, matrix systems, and reservoir systems.

In a matrix system, the fragrance is dissolved or dispersed in a polymermatrix or particle. Perfumes, for example, may be 1) dispersed into thepolymer prior to formulating into the product or 2) added separatelyfrom the polymer during or after formulation of the product. Diffusionof perfume from the polymer is a common trigger that allows or increasesthe rate of perfume release from a polymeric matrix system that isdeposited or applied to the desired surface (situs), although many othertriggers are know that may control perfume release. Absorption and/oradsorption into or onto polymeric particles, films, solutions, and thelike are aspects of this technology. Nano, or micro-particles, composedof organic materials (e.g., latexes) are examples. Suitable particlesinclude a wide range of materials including, but not limited topolyacetal, polyacrylate, polyacrylic, polyacrylonitrile, polyamide,polyaryletherketone, polybutadiene, polybutylene, polybutyleneterephthalate, polychloroprene, poly ethylene, polyethyleneterephthalate, polycyclohexylene dimethylene terephthalate,polycarbonate, polychloroprene, polyhydroxyalkanoate, polyketone,polyester, polyethylene, polyetherimide, polyethersulfone,polyethylenechlorinates, polyimide, polyisoprene, polylactic acid,polymethylpentene, polyphenylene oxide, polyphenylene sulfide,polyphthalamide, polypropylene, polystyrene, polysulfone, polyvinylacetate, polyvinyl chloride, as well as polymers or copolymers based onacrylonitrile-butadiene, cellulose acetate, ethylene-vinyl acetate,ethylene vinyl alcohol, styrene-butadiene, vinyl acetate-ethylene, andmixtures thereof.

A “standard” matrix system refers to systems that are “pre-loaded” withthe intent of keeping the pre-loaded perfume associated with the polymeruntil the moment, or moments of, perfume release. Such polymers may alsosuppress the neat product odor and provide a bloom and/or longevitybenefit depending on the rate of perfume release. One challenge withsuch systems is to achieve the ideal balance between 1) in-productstability (keeping perfume inside carrier until you need it) and 2)timely release (during use or from dry situs). Achieving such stabilityis particularly important during in-product storage and product aging.This challenge is particularly apparent for aqueous-based,surfactant-containing products, such as heavy duty liquid laundrydetergents. Many “Standard” matrix systems available effectively become“Equilibrium” systems when formulated into aqueous-based products. Onemay select an “Equilibrium” system or a Reservoir system, which hasacceptable in-product diffusion stability and available triggers forrelease (e.g., friction). “Equilibrium” systems are those in which theperfume and polymer may be added separately to the product, and theequilibrium interaction between perfume and polymer leads to a benefitat one or more consumer touch points (versus a free perfume control thathas no polymer-assisted delivery technology). The polymer may also bepre-loaded with perfume; however, part or all of the perfume may diffuseduring in-product storage reaching an equilibrium that includes havingdesired perfume raw materials (PRMs) associated with the polymer. Thepolymer then carries the perfume to the surface, and release istypically via perfume diffusion. The use of such equilibrium systempolymers has the potential to decrease the neat product odor intensityof the neat product (usually more so in the case of pre-loaded standardsystem). Deposition of such polymers may serve to “flatten” the releaseprofile and provide increased longevity. As indicated above, suchlongevity would be achieved by suppressing the initial intensity and mayenable the formulator to use more high impact or low odor detectionthreshold (ODT) or low Kovats Index (KI) PRMs to achieve FMOT benefitswithout initial intensity that is too strong or distorted. It isimportant that perfume release occurs within the time frame of theapplication to impact the desired consumer touch point or touch points.Suitable micro-particles and micro-latexes as well as methods of makingsame may be found in U.S. Pre-Grant Publication No. 2005/0003980 A1.Matrix systems also include hot melt adhesives and perfume plastics. Inaddition, hydrophobically modified polysaccharides may be formulatedinto the perfumed product to increase perfume deposition and/or modifyperfume release. All such matrix systems, including for examplepolysaccharides and nanolatexes may be combined with other PDTs,including other PAD systems such as PAD reservoir systems in the form ofa perfume microcapsule (PMC). Polymer Assisted Delivery (PAD) matrixsystems may include those described in the following references: U.S.Pre-Grant Publication No. 2004/0110648 A1 and U.S. Pat. No. 6,531,444.

Silicones are also examples of polymers that may be used as PDT, and canprovide perfume benefits in a manner similar to the polymer-assisteddelivery “matrix system”. Such a PDT is referred to as silicone-assisteddelivery (SAD). One may pre-load silicones with perfume, or use them asan equilibrium system as described for PAD. Suitable silicones as wellas making same may be found in U.S. Pre-Grant Publication No.2005/0143282 A1. Functionalized silicones may also be used as describedin U.S. Pre-Grant Publication No. 2006/003913 A1. Examples of siliconesinclude polydimethylsiloxane and polyalkyldimethylsiloxanes. Otherexamples include those with amine functionality, which may be used toprovide benefits associated with amine-assisted delivery (AAD) and/orpolymer-assisted delivery (PAD) and/or amine-reaction products (ARP).Other such examples may be found in U.S. Pre-Grant Publication No.2005/0003980 A1.

Reservoir systems are also known as a core-shell type technology, or onein which the fragrance is surrounded by a perfume release controllingmembrane, which may serve as a protective shell. The material inside themicrocapsule is referred to as the core, internal phase, or fill,whereas the wall is sometimes called a shell, coating, or membrane.Microparticles or pressure sensitive capsules or microcapsules areexamples of this technology. Microcapsules of the current invention areformed by a variety of procedures that include, but are not limited to,coating, extrusion, spray-drying, interfacial, in-situ and matrixpolymerization. The possible shell materials vary widely in theirstability toward water. Among the most stable are polyoxymethyleneurea(PMU)-based materials, which may hold certain PRMs for even long periodsof time in aqueous solution (or product). Such systems include but arenot limited to urea-formaldehyde and/or melamine-formaldehyde.Gelatin-based microcapsules may be prepared so that they dissolvequickly or slowly in water, depending for example on the degree ofcross-linking. Many other capsule wall materials are available and varyin the degree of perfume diffusion stability observed. Without wishingto be bound by theory, the rate of release of perfume from a capsule,for example, once deposited on a surface is typically in reverse orderof in-product perfume diffusion stability. As such, urea-formaldehydeand melamine-formaldehyde microcapsules for example, typically require arelease mechanism other than, or in addition to, diffusion for release,such as mechanical force (e.g., friction, pressure, shear stress) thatserves to break the capsule and increase the rate of perfume (fragrance)release. Other triggers include melting, dissolution, hydrolysis orother chemical reaction, electromagnetic radiation, and the like.Suitable capsule wall materials include, in addition to aminoplasts,polyvinyl alcohol, polyvinyl pyrrolidone, polyethylene glycol,polysaccharides and modified polysaccharides, gel forming proteins,modified celluloses such as carboxymethylcelluloses andhydroxyethylcelluloses, polyacrylates, polyureas, polyurethanes andmixtures thereof. The capsules may be further coated with an additionalcoating that can improve the deposition and/or retention of the capsuleon the desired surface. Suitable coating materials include a cationicpolymer selected from the group consisting of selected from the groupconsisting of polysaccharides, cationically modified starch,cationically modified guar, polysiloxanes, poly diallyl dimethylammonium halides, copolymers of poly diallyl dimethyl ammonium chlorideand vinyl pyrrolidone, acrylamides, imidazoles, imidazolinium halides,imidazolium halides, poly vinyl amine, copolymers of poly vinyl amineand N-vinyl formamide to the surface of the capsule to form acationically coated polymer encapsulated material. Typical capsules havea diameter of 1 micron to 500 microns. The use of pre-loadedmicrocapsules requires the proper ratio of in-product stability andin-use and/or on-surface (on-situs) release, as well as proper selectionof PRMs. Microcapsules that are based on urea-formaldehyde and/ormelamine-formaldehyde are relatively stable, especially in near neutralaqueous-based solutions. These materials may require a friction triggerwhich may not be applicable to all product applications. Othermicrocapsule materials (e.g., gelatin) may be unstable in aqueous-basedproducts and may even provide reduced benefit (versus free perfumecontrol) when in-product aged.

Molecule-Assisted Delivery (MAD)

Non-polymer materials or molecules may also serve to improve thedelivery of perfume. Without wishing to be bound by theory, perfume maynon-covalently interact with organic materials, resulting in altereddeposition and/or release. Non-limiting examples of such organicmaterials include but are not limited to hydrophobic materials such asorganic oils, waxes, mineral oils, petrolatum, fatty acids or esters,sugars, surfactants, liposomes and even other perfume raw material(perfume oils), as well as natural oils, including body and/or othersoils. Perfume fixatives are yet another example. In one example,non-polymeric materials or molecules have a C Log P greater than about2. Molecule-Assisted Delivery (MAD) may also include those described inU.S. Pat. No. 7,119,060.

Fiber-Assisted Delivery (FAD):

The choice or use of a situs itself may serve to improve the delivery ofperfume. In fact, the situs itself may be a perfume delivery technology.For example, different fabric types such as cotton or polyester willhave different properties with respect to ability to attract and/orretain and/or release perfume. The amount of perfume deposited on or infibers may be altered by the choice of fiber, and also by the history ortreatment of the fiber, as well as by any fiber coatings or treatments.Fibers may be woven and non-woven as well as natural or synthetic.Natural fibers include those produced by plants, animals, and geologicalprocesses, and include but are not limited to cellulose materials suchas cotton, linen, hemp jute, flax, ramie, and sisal, and fibers used tomanufacture paper and cloth. Fiber-Assisted Delivery may consist of theuse of wood fiber, such as thermomechanical pulp and bleached orunbleached kraft or sulfite pulps. Animal fibers consist largely ofparticular proteins, such as silk, sinew, catgut and hair (includingwool). Polymer fibers based on synthetic chemicals include but are notlimited to polyamide nylon, PET or PBT polyester, phenol-formaldehyde(PF), polyvinyl alcohol fiber (PVOH), polyvinyl chloride fiber (PVC),polyolefins (PP and PE), and acrylic polymers. All such fibers may bepre-loaded with a perfume, and then added to a product that may or maynot contain free perfume and/or one or more perfume deliverytechnologies. In one example, the fibers may be added to a product priorto being loaded with a perfume, and then loaded with a perfume by addinga perfume that may diffuse into the fiber, to the product. Withoutwishing to be bound by theory, the perfume may absorb onto or beadsorbed into the fiber, for example, during product storage, and thenbe released at one or more moments of truth or consumer touch points.

Amine-Assisted Delivery (AAD)

The amine-assisted delivery technology approach utilizes materials thatcontain an amine group to increase perfume deposition or modify perfumerelease during product use. There is no requirement in this approach topre-complex or pre-react the perfume raw material(s) and amine prior toaddition to the product. In one example, amine-containing AAD materialssuitable for use herein may be non-aromatic; for example,polyalkylimine, such as polyethyleneimine (PEI), or polyvinylamine(PVAm), or aromatic, for example, anthranilates. Such materials may alsobe polymeric or non-polymeric. In one example, such materials contain atleast one primary amine. This technology will allow increased longevityand controlled release also of low ODT perfume notes (e.g., aldehydes,ketones, enones) via amine functionality, and delivery of other PRMs,without being bound by theory, via polymer-assisted delivery forpolymeric amines. Without technology, volatile top notes can be lost tooquickly, leaving a higher ratio of middle and base notes to top notes.The use of a polymeric amine allows higher levels of top notes and otherPRMS to be used to obtain freshness longevity without causing neatproduct odor to be more intense than desired, or allows top notes andother PRMs to be used more efficiently. In one example, AAD systems areeffective at delivering PRMs at pH greater than about neutral. Withoutwishing to be bound by theory, conditions in which more of the amines ofthe AAD system are deprotonated may result in an increased affinity ofthe deprotonated amines for PRMs such as aldehydes and ketones,including unsaturated ketones and enones such as damascone. In anotherexample, polymeric amines are effective at delivering PRMs at pH lessthan about neutral. Without wishing to be bound by theory, conditions inwhich more of the amines of the AAD system are protonated may result ina decreased affinity of the protonated amines for PRMs such as aldehydesand ketones, and a strong affinity of the polymer framework for a broadrange of PRMs. In such an example, polymer-assisted delivery may bedelivering more of the perfume benefit; such systems are a subspecies ofAAD and may be referred to as Amine-Polymer-Assisted Delivery or APAD.In some cases when the APAD is employed in a composition that has a pHof less than seven, such APAD systems may also be consideredPolymer-Assisted Delivery (PAD). In yet another example, AAD and PADsystems may interact with other materials, such as anionic surfactantsor polymers to form coacervate and/or coacervates-like systems. Inanother example, a material that contains a heteroatom other thannitrogen, for example sulfur, phosphorus or selenium, may be used as analternative to amine compounds. In yet another example, theaforementioned alternative compounds can be used in combination withamine compounds. In yet another example, a single molecule may comprisean amine moiety and one or more of the alternative heteroatom moieties,for example, thiols, phosphines and selenols. Suitable AAD systems aswell as methods of making same may be found in U.S. Pat. No. 6,103,678.

Cyclodextrin Delivery System (CD)

This technology approach uses a cyclic oligosaccharide or cyclodextrinto improve the delivery of perfume. Typically a perfume and cyclodextrin(CD) complex is formed. Such complexes may be preformed, formed in-situ,or formed on or in the situs. Without wishing to be bound by theory,loss of water may serve to shift the equilibrium toward the CD-Perfumecomplex, especially if other adjunct ingredients (e.g., surfactant) arenot present at high concentration to compete with the perfume for thecyclodextrin cavity. A bloom benefit may be achieved if water exposureor an increase in moisture content occurs at a later time point. Inaddition, cyclodextrin allows the perfume formulator increasedflexibility in selection of PRMs. Cyclodextrin may be pre-loaded withperfume or added separately from perfume to obtain the desired perfumestability, deposition or release benefit. Suitable cyclodextrin deliverysystems as well as methods of making the same may be found in U.S.Pre-Grant Publication No. 2006/0263313 A1.

Starch Encapsulated Accord (SEA)

The use of a starch encapsulated accord (SEA) technology allows one tomodify the properties of the perfume, for example, by converting aliquid perfume into a solid by adding ingredients such as starch. Thebenefit includes increased perfume retention during product storage,especially under non-aqueous conditions. Upon exposure to moisture, aperfume bloom may be triggered. Benefits at other moments of truth mayalso be achieved because the starch allows the product formulator toselect PRMs or PRM concentrations that normally cannot be used withoutthe presence of SEA. Another technology example includes the use ofother organic and inorganic materials, such as silica to convert perfumefrom liquid to solid. Suitable SEAs as well as methods of making samemay be found in U.S. Pat. No. 6,458,754 B1.

Inorganic Carrier Delivery System (ZIC)

This technology relates to the use of porous zeolites or other inorganicmaterials to deliver perfumes. Perfume-loaded zeolite may be used withor without adjunct ingredients used for example to coat theperfume-loaded zeolite (PLZ) to change its perfume release propertiesduring product storage or during use or from the dry situs. Suitablezeolite and inorganic carriers as well as methods of making same may befound in U.S. Pre-Grant Publication No. 2005/0003980 A1. Silica isanother form of ZIC. Another example of a suitable inorganic carrierincludes inorganic tubules, where the perfume or other active materialis contained within the lumen of the nano- or micro-tubules. Preferably,the perfume-loaded inorganic tubule (or Perfume-Loaded Tubule or PLT) isa mineral nano- or micro-tubule, such as halloysite or mixtures ofhalloysite with other inorganic materials, including other clays. ThePLT technology may also comprise additional ingredients on the insideand/or outside of the tubule for the purpose of improving in-productdiffusion stability, deposition on the desired situs or for controllingthe release rate of the loaded perfume. Monomeric and/or polymericmaterials, including starch encapsulation, may be used to coat, plug,cap, or otherwise encapsulate the PLT. Suitable PLT systems as well asmethods of making same may be found in U.S. Pat. No. 5,651,976.

Pro-Perfume (PP)

This technology refers to perfume technologies that result from thereaction of perfume materials with other substrates or chemicals to formmaterials that have a covalent bond between one or more PRMs and one ormore carriers. The PRM is converted into a new material called a pro-PRM(i.e., pro-perfume), which then may release the original PRM uponexposure to a trigger such as water or light. Pro-perfumes may provideenhanced perfume delivery properties such as increased perfumedeposition, longevity, stability, retention, and the like. Pro-perfumesinclude those that are monomeric (non-polymeric) or polymeric, and maybe pre-formed or may be formed in-situ under equilibrium conditions,such as those that may be present during in-product storage or on thewet or dry situs.

Nonlimiting examples of pro-perfumes include Michael adducts (e.g.,beta-amino ketones), aromatic or non-aromatic imines (Schiffs Bases),oxazolidines, beta-keto esters, and orthoesters. Another exampleincludes compounds comprising one or more beta-oxy or beta-thio carbonylmoieties capable of releasing a PRM, for example, an alpha,beta-unsaturated ketone, aldehyde or carboxylic ester. The typicaltrigger for perfume release is exposure to water; although othertriggers may include enzymes, heat, light, pH change, autoxidation, ashift of equilibrium, change in concentration or ionic strength andothers. For aqueous-based products, light-triggered pro-perfumes areparticularly suited. Such photo-pro-perfumes (PPPs) include but are notlimited to those that release coumarin derivatives and perfumes and/orpro-perfumes upon being triggered. The released pro-perfume may releaseone or more PRMs by means of any of the above mentioned triggers. In oneexample, the photo-pro-perfume releases a nitrogen-based pro-perfumewhen exposed to a light and/or moisture trigger. In another example, thenitrogen-based pro-perfume, released from the photo-pro-perfume,releases one or more PRMs selected, for example, from aldehydes, ketones(including enones) and alcohols. In still another example, the PPPreleases a dihydroxy coumarin derivative. The light-triggeredpro-perfume may also be an ester that releases a coumarin derivative anda perfume alcohol. In one example the pro-perfume is a dimethoxybenzoinderivative as described in U.S. Pre-Grant Publication No. 2006/0020459A1. In another example the pro-perfume is a 3′,5′-dimethoxybenzoin (DMB)derivative that releases an alcohol upon exposure to electromagneticradiation. In yet another example, the pro-perfume releases one or morelow ODT PRMs, including tertiary alcohols such as linalool,tetrahydrolinalool, or dihydromyrcenol. Suitable pro-perfumes andmethods of making same can be found in U.S. Pat. No. 7,018,978 B2.

An amine reaction product (“ARP”) is a subclass or species of PP. Onemay also use “reactive” polymeric amines in which the aminefunctionality is pre-reacted with one or more PRMs to form an aminereaction product (ARP). Typically the reactive amines are primary and/orsecondary amines, and may be part of a polymer or a monomer(non-polymer). Such ARPs may also be mixed with additional PRMs toprovide benefits of polymer-assisted delivery and/or amine-assisteddelivery. Nonlimiting examples of polymeric amines include polymersbased on polyalkylimines, such as polyethyleneimine (PEI), orpolyvinylamine (PVAm). Nonlimiting examples of monomeric (non-polymeric)amines include hydroxyl amines, such as 2-aminoethanol and its alkylsubstituted derivatives, and aromatic amines such as anthranilates. TheARPs may be premixed with perfume or added separately in leave-on orrinse-off applications. In another example, a material that contains aheteroatom other than nitrogen, for example oxygen, sulfur, phosphorusor selenium, may be used as an alternative to amine compounds. In yetanother example, the aforementioned alternative compounds can be used incombination with amine compounds. In yet another example, a singlemolecule may comprise an amine moiety and one or more of the alternativeheteroatom moieties, for example, thiols, phosphines and selenols. Thebenefit may include improved delivery of perfume as well as controlledperfume release. Suitable ARPs as well as methods of making same can befound in U.S. Pat. No. 6,413,920 B1.

The perfumes disclosed herein can be used as the perfume componentpro-perfume compounds that contain sulfur. The term “pro-perfumecompound” herein refers to compounds resulting from the chemical bondingof perfume raw materials (PRMs) with materials that comprise sulfur. Thepro-perfume compound can release the original PRM (i.e., pre-converted)upon exposure to a trigger such as water or light or atmospheric oxygen.Suitable methods of making the same can be found in U.S. Pat. No.7,018,978.

Odor Entrappers

The composition can include an odor entrapper. Suitable odor entrappersfor use herein include, for example, solubilized, water-soluble,uncomplexed cyclodextrin. As used herein, the term “cyclodextrin”includes any of the known cyclodextrins such as unsubstitutedcyclodextrins containing from six to twelve glucose units, especially,alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and/or theirderivatives and/or mixtures thereof. The alpha-cyclodextrin consists ofsix glucose units, the beta-cyclodextrin consists of seven glucoseunits, and the gamma-cyclodextrin consists of eight glucose unitsarranged in a donut-shaped ring. The specific coupling and conformationof the glucose units give the cyclodextrins a rigid, conical molecularstructure with a hollow interior of a specific volume. The “lining” ofthe internal cavity is formed by hydrogen atoms and glycosidic bridgingoxygen atoms, therefore this surface is fairly hydrophobic. The uniqueshape and physical-chemical property of the cavity enable thecyclodextrin molecules to absorb (form inclusion complexes with) organicmolecules or parts of organic molecules which can fit into the cavity.Many perfume molecules can fit into the cavity.

Cyclodextrin molecules are described in U.S. Pat. No. 5,714,137, andU.S. Pat. No. 5,942,217. Suitable levels of cyclodextrin are from about0.1% to about 5%, alternatively from about 0.2% to about 4%,alternatively from about 0.3% to about 3%, alternatively from about 0.4%to about 2%, by weight of the composition.

The composition can include a preservative. The preservative is includedin an amount sufficient to prevent spoilage or prevent growth ofinadvertently added microorganisms for a specific period of time, butnot sufficient enough to contribute to the odor neutralizing performanceof the composition. In other words, the preservative is not being usedas the antimicrobial compound to kill microorganisms on the surface ontowhich the composition is deposited in order to eliminate odors producedby microorganisms. Instead, it is being used to prevent spoilage of thecomposition in order to increase shelf-life.

The preservative can be any organic preservative material which will notcause damage to fabric appearance, e.g., discoloration, coloration,bleaching. Suitable water-soluble preservatives include organic sulfurcompounds, halogenated compounds, cyclic organic nitrogen compounds, lowmolecular weight aldehydes, parabens, propane diaol materials,isothiazolinones, quaternary compounds, benzoates, low molecular weightalcohols, dehydroacetic acid, phenyl and phenoxy compounds, or mixturesthereof.

Such ZAG complexes are described in U.S. Pat.No. 3,792,068; Great Britain Patent Application 2,144,992; and U.S. Pat.No. 4,120,948, disclosures of which are incorporated herein by referencefor the limited purpose of describing ZAG complexes.

Also suitable for use herein are enhanced efficacy aluminum-zirconiumchlorohydrex-amino acid which typically has the empirical formulaAl_(n)Zr(OH)_([3n+4−m(n+1)])(Cl)_([m(n+1)])-AA_(q) where n is 2.0 to10.0, preferably 3.0 to 8.0; m is about 0.48 to about 1.11 (whichcorresponds to M:Cl approximately equal to 2.1-0.9), preferably about0.56 to about 0.83 (which corresponds to M:Cl approximately equal to1.8-1.2); q is about 0.8 to about 4.0, preferably about 1.0 to 2.0; andAA is an amino acid such as glycine, alanine, valine, serine, leucine,isoleucine, β-alanine, cysteine, β-amino-n-butyric acid, orγ-amino-n-butyric acid, preferably glycine. These salts also generallyhave some water of hydration associated with them, typically on theorder of 1 to 5 moles per mole of salt (typically, about 1% to about16%, more typically about 4% to about 13% by weight). These salts aregenerally referred to as aluminum-zirconium trichlorohydrex ortetrachlorohydrex when the Al:Zr ratio is between 2 and 6 and asaluminum-zirconium pentachlorohydrex or octachlorohydrex when the Al:Zrratio is between 6 and 10. The term “aluminum-zirconium chlorohydrex” isintended to embrace all of these forms. The preferred aluminum-zirconiumsalt is aluminum-zirconium chlorohydrex-glycine. Additional examples ofsuitable high efficacy antiperspirant actives can include AluminumZirconium Pentachlorohydrex Glycine, Aluminum Zirconium OctachlorohydrexGlycine, or a combination thereof. These high efficacy actives are morefully described in U.S. App. Pub. No. 2007/0003499 by Shen et al. filedJun. 30, 2005.

“Volatile silicone” as used herein refers to those silicone materialswhich have measurable vapor pressure under ambient conditions.Nonlimiting examples of suitable volatile silicones are described inTodd et al., “Volatile Silicone Fluids for Cosmetics”, Cosmetics andToiletries, 91:27-32 (1976), which descriptions are incorporated hereinby reference. Preferred volatile silicone materials are those havingfrom about 3 to about 7, preferably from about 4 to about 5, siliconatoms.

Cyclic volatile silicones are preferred for use in the antiperspirantcompositions herein, and include those represented by the formula:

Linear volatile silicone materials suitable for use in theantiperspirant compositions include those represented by the formula:

wherein n is from about 1 to about 7, preferably from about 2 to about3. These linear silicone materials will generally have viscosities ofless than about 5 centistokes at 25° C. Specific examples of volatilesilicone solvents suitable for use in the antiperspirant compositionsinclude, but are not limited to, Cyclomethicone D-5 (commerciallyavailable from G. E. Silicones), Dow Corning 344, Dow Corning 345 andDow Corning 200 (commercially available from Dow Corning Corp.), GE 7207and 7158 (commercially available from General Electric Co.) andSWS-03314 (commercially available from SWS Silicones Corp.).

Gellant Material

The soft solid can include a gellant material comprising fatty alcoholshaving from about 20 to about 60 carbon atoms, or combinations thereof,at concentrations ranging from about 0.1% to about 8% by weight of thecomposition. The gellant material, when combined with the volatilesilicone solvent described hereinbefore, provides the composition with aphysically stable structure within which the particulate antiperspirantmaterials are dispersed, and maintained as such over an extended periodof time.

Specifically, the gellant material can comprise saturated orunsaturated, substituted or unsubstituted, fatty alcohols or mixtures offatty alcohols having from about 20 to about 60 carbons atoms,preferably from about 20 to about 40 carbon atoms. Preferred arecombinations of the fatty alcohols. The fatty alcohol gellants arepreferably saturated, unsubstituted monohydric alcohols or combinationsthereof, which have a melting point of at less than about 110° C., morepreferably from about 60° to about 110° C., even more preferably betweenabout 100° C. and 110° C.

It has been found that this fatty alcohol-based gellant material, whencombined with volatile silicone solvents provides a stable structure formaintaining a dispersion of particulate antiperspirant material in atopical formulation without the necessity of using conventionalparticulate thickening agents. This gellant material is especiallyuseful in maintaining the physical stability of particulate dispersionscontaining higher concentrations of volatile silicone solvents.

It was also found that penetration force values for the antiperspirantcompositions can be controlled by adjusting total fatty alcoholconcentrations. In controlling penetration force values in this manner,there is no longer a need to use organic solvents or thickening agentsto control penetration force values, which solvents or thickening agentsoften add cost to the formulation, introduce additional compatibilityissues, and often contribute undesirable cosmetics such as prolongedstickiness, difficulty in ease of spreading, increased dry-down timesand reduced dry feel after application.

Specific concentrations of the gellant materials can be selectedaccording to the desired penetration force value. For roll-onformulations having a penetration force value of from about 20gram·force to about 100 gram·force, gellant material concentrationspreferably range from about 0.1% to about 3%, preferably from about 1.5%to about 3%, by weight of the antiperspirant composition. For othercream formulations, including those formulations suitable for use incream applicator devices, which have a penetration force value of fromabout 100 gram·force to about 500 gram·force, gellant materialconcentrations preferably range from about 3% to about 8%, preferablyfrom about 3% to about 6%, by weight of the antiperspirant composition.

Arepresentative, non-limiting list of emollient oils includes CETIOL CC(dicaprylyl carbonate), CETIOL OE (dicaprylyl ether), CETIOL S(diethylhexylcyclohexane), and CETIOL B (dibutyl adipate), all of whichare available from Cognis, and LEXFEEL 7 (neopentyl glycol diheptanoate)from Inolex. In certain examples, the organic emollient oils have aviscosity of less than 50 centistokes at 25° C. The term “organicemollient oil” as used herein means silicon-free emollient oils that areliquid at 25° C., and that are safe and light to skin and can bemiscible with volatile silicone oils (as described above) and theantiperspirant active-alcohol solution in the concentration rangesdescribed below.

The oil or mixture of oils is generally included in the concentrateformulas at a level of from about 5% to about 45%, by weight of theconcentrate. This viscosity ranges noted above in connection with thedifferent classes of oil can facilitate desired spray rates andpatterns, and can help minimize nozzle clogging. To provide desired skinfeel, minimal nozzle clogging, and good concentrate stability, the ratioof alcohol to volatile silicone oil is preferably greater than 1.0,1.35, or 1.5. And in examples having both a volatile silicone oil and anorganic emollient oil, the ratio of alcohol to total oil is preferablygreater than or equal to about 0.90. The oils in certain examples aremiscible with the alcohol and antiperspirant active solution. Althoughvarious levels of miscibility are acceptable, the oils are preferablymiscible enough with the alcohol and antiperspirant active solution toyield a concentrate having a clear appearance.

The antiperspirant compositions can also include residue-masking agentsand propellants as discussed above.

Test Methods

The Degree of Habituation to an antiperspirant composition containing aperfume can be determined by exposing a human panel to daily exposuresof the perfume over a four week period. The Degree of Habituation can becalculated at both the week two and week four time points, relative tothe initial baseline time point.

For each exposure panel test, more than 15 panelists are recruited, andthen exposed to the test scent in a manner, frequency, and concentrationindicated by the intended product end use, but including at least oneexposure per day every day for four consecutive weeks. The perfumeexposure must be sufficient that the panelists can detect the perfume ofinterest being delivered from the product or perfume delivery systemcontained within the product. The criteria for recruitment onto theexposure panel requires that panelists be typical consumers of theproduct in question, who agree to use the scent being tested, arenon-smokers, and free of nasal congestion and allergies. The degree ofhabituation is calculated and reported as the percent change in the OdorDetection Threshold (ODT) value at week 2 and at week 4, versus theinitial baseline ODT value. Since the degree of habituation is arelative measure, it accommodates the variation in absolute ODT valueswhich can arise between different testing laboratories.

Raw materials and finished products comprising them can be used inconjunction in order to determine the degree of habituation. Forexample, daily exposures to the panelists may involve the use of afinished product while the ODT test measurements may involve the use ofthe respective neat perfume or PRMs. The conditions selected for use ineither the daily exposures or in the ODT testing must be applieduniformly across all panelists, and remain unchanged for the entirety ofthe testing period. When the test perfume materials are available intheir simple forms i.e., PRMs, neat perfumes, or fine fragrances,unincorporated into complex products or delivery systems, then the ODTtest is to be conducted with these simple forms via an olfactometer, asthis is the preferred method. When these simple forms of the testperfume materials are inaccessible for testing, then the ODT test may beconducted with finished products or complex formulations comprising thetest perfume materials. Presentation devices other than an olfactometermay be required when conducting the ODT testing on finished products orcomplex formulations, and may include devices such as sniff cups,headspace chambers and capped bottles, as allowed for in the test methodASTM E679-04 described below.

The ODT value for each panelist is determined at each of three timepoints the during four week daily exposure period, namely; at an initialbaseline, at two weeks, and at four weeks. The ODT values are alwaysdetermined in accordance with test method ASTM E679-04 (StandardPractice for Determination of Odor and Taste Thresholds by aForced-Choice Ascending Concentration Series of Limits) as reapproved in2011 except, the following replaces the protocol of such test method'sSub-articles 4.4, 8.2 and 8.3.

Sub-article 4.4, Individual best-estimate values of the threshold arederived from the pattern of correct/incorrect responses producedseparately by each panelist. The group average ODT value at a given timepoint is derived by fitting the entire data set from all panelists atthat time point to a Log Logistic Regression Model.

Sub-article 8.2, If the concentration range has been correctly selected,it is not necessary that all panelists judge correctly within the rangeof concentration steps provided. Thus, the representation of thepanelists' judgments as in 8.1 need not terminate with two or moreconsecutive plusses (+).

Sub-article 8.3, Since there is a finite probability that a correctanswer will occur by chance alone, it is important that a panelistrepeat the test three times. Panelists who fail the test at the highestconcentration, are deemed anomic to the test material and their responseis removed from the data set.

Additionally, the following selections are made in accordance with thetest method's sub-articles 1.3, 1.4, 1.6, 1.7, and 4.1, and specifiedhere as per sub-article 9.3.

Sub-article 1.3, The threshold is characterized as being a) onlydetection (awareness) that a very small amount of added substance ispresent but not necessarily recognizable.

Sub-article 1.4, When the preferred method is being conducted, namelyusing a simple perfume form presented via olfactometer, then thepresentation medium is an air and pure nitrogen mix. When testingfinished or complex products, alternative presentation media may beused, such as air.

Sub-article 1.6, When the preferred method is being conducted, namelyusing a simple perfume form presented via olfactometer, then thephysical method of presentation is at a rate of 40 L/min. When testingfinished or complex products, alternative presentation devices may beused, including but not limited to sniff cups, headspace chambers orcapped bottles.

Sub-article 1.7, Presentation is made to a panel of greater than 15panelists, who are participating in the daily exposure panel.

Sub-article 4.1, Eight scale steps are used, with each step having anindividual predetermined dilution factor suitable for the stimuli beingtested, at a temperature of 35° C. PRM or neat perfume stimuli aretypically introduced to the olfactometer system in the neat form via apump syringe. Sometimes a dilution of the stimuli with ethanol isneeded.

The group average ODT values from the three time points are used tocalculate the degree of habituation. The degree of habituation isreported for 2 specific time points, as the percent change in groupaverage ODT at one time point, relative to the group average ODT at theinitial baseline time point. The degree of habituation is determined atthe time points of: 2 weeks and 4 weeks, of the four week daily exposureperiod, using the following formula:Degree of Habituation (percent change in ODT) at Time X=((Group AverageODT_((Time X))−Group Average ODT_((Baseline))/Group AverageODT_((Baseline)))×100where Time X is either 2 weeks, or 4 weeks, of repeated daily exposure.Anti-Habituation IndexA perfume is considered to have an anti-habituation index of:For a Two Week Test

-   -   Zero (0) when the Degree of Habituation after 2 weeks of        exposure to said perfume is from about 150% to 25%    -   One (1) when the Degree of Habituation after 2 weeks of exposure        to said perfume is less than 25% but greater than 10%;    -   Two (2) when the Degree of Habituation after 2 weeks of exposure        to said perfume is from 10% to 0%; or    -   Three (3) when the Degree of Habituation after 2 weeks of        exposure to said perfume is less than 0% to about −25%.    -   Four (4) when the Degree of Habituation after 2 weeks of        exposure to said perfume is less than −25% to about −500%        For a Four Week Test    -   Zero (0) when the Degree of Habituation after 4 weeks of        exposure to said perfume is from about 150% to 25%    -   One (1) when the Degree of Habituation after 4 weeks of exposure        to said perfume is less than 25% but greater than 10%;    -   Two (2) when the Degree of Habituation after 4 weeks of exposure        to said perfume is from 10% to 0%; or    -   Three (3) when the Degree of Habituation after 4 weeks of        exposure to said perfume is less than 0% to about −25%.    -   Four (4) when the Degree of Habituation after 4 weeks of        exposure to said perfume is less than −25% to about −500%

The formulations defined above various perfume formulations. Formula VIIcontains a base control perfume formulation PD. Formulas VIII, and IXeach contain additional components. More specifically, formula VIIIcontaining Perfume 2.A Perfume 2.A includes a three component perfumeaccord composed of perfume raw materials containing a pyrazine, nitrile,and amine moieties. Formula IX containing Perfume 2.B which includes athree component perfume accord composed of perfume raw materialsconsisting of menthol and menthol derivatives.

Approximately 20 test subjects per usage group were recruited for thestudy. The test subjects placed in the study were assessed for theirbaseline threshold intensity according to the Odor Detection Threshold(ODT) method defined above for the perfume of interest that was in theproduct. Test subjects were placed in five study groups with anantiperspirant/deodorant according to formulas VII, VIII, and IX andinstructed to apply 2 clicks per underarm (approximately 0.4 g perunderarm) throughout the four week study period, using no other underarmproducts throughout the duration of the study. Their Odor DetectionThreshold (ODT) was measured again after 2 weeks of usage, and againafter 4 weeks of usage. The average Odor Detection Threshold wascalculated for each usage group.

The results indicate that the Odor Detection Threshold remains unchangedfor the usage group using Formula VII (comparative perfume) after 4weeks of usage. The Odor Detection Threshold increases significantlyabove baseline (test subjects are less sensitive) for the usage groupusing Formula IX (perfume containing menthol and menthol derivatives)after 4 weeks of usage, indicating habituation. One surprising result isthat the base perfume's (Formula VII) anti-habituation index of two (2)from the two week test moved, when anti-habituation materials were added(formulation VIII) to an anti-habituation index for such formula of 4under the two week test when the additional perfume raw materials(s) asspecified in Perfume 2.A are added. Another surprising result is thatthe base perfume's (Formula VII) anti-habituation index of three (3)from the four week test moved, when anti-habituation materials wereadded (formulation VIII) to an anti-habituation index of 4 under thefour week test when the additional perfume raw materials(s) as specifiedin Perfume 2.A are added. Such materials were a pyrazine-nitrile-amineaccord.

The above formulations VII, VIII, and IX, were rated by consumers in ausage test. 10 independent test groups of approximately 20 panelistswere instructed to use the product as they normally would. 5 of the testgroups, each using one of the formulas VII, VIII, and IX were instructedto use the product for a single day, and rate their overall opinion ofthe product after using the product based on a 5 point scale.(100=Excellent, 75=Very Good, 50=Good, 25=Fair, 0=Poor). Separately, theother 5 test groups, each using one of the formulas VII, VIII, and IXwere instructed to use the product for a four week period, and ratetheir overall opinion of the product based on the same 5 point scaledefined above. Results indicate that formulas are rated parity after asingle day usage, but the resistance to habituation shown in Table 4yields an improved usage rating, only after a four week period.

The formulations defined in Table 7 are various perfume formulations tobe used in Formula X. Seven unique formulas were made for Formula X,each containing 0.9% of one of the perfumes from example number X.Athrough X.G, as defined in Table 7.

Approximately 20 test subjects per usage group were recruited for thestudy. The test subjects placed in the study were assessed for theirbaseline threshold intensity according to the Odor Detection Threshold(ODT) method defined above for the perfume of interest that was in theproduct. Test subjects were placed in nineteen study groups with anantiperspirant/deodorant and instructed to apply 2 clicks per underarm(approximately 0.4 g per underarm) throughout the four week studyperiod, using no other underarm products throughout the duration of thestudy. Their Odor Detection Threshold (ODT) was measured again after 4weeks of usage. The average Odor Detection Threshold was calculated foreach usage group. Results are shown below.

The results indicate that the Odor Detection Threshold increasessignificantly above baseline (test subjects are less sensitive) for theusage group using the formula containing the base perfume PD only, whichwas void of all sulfur and nitrogen PRM's after 4 weeks of usage,indicating habituation. Surprisingly, all components containing nitrogenchemistry showed improvement relative to the control.

It is believed that the differences seen from Example 1, in which thebase perfume had an anti-habituation index of 3 in the four week test,vs. Example 2, in which the base perfume had significant increase in ODTis beyond what is expected of individual variation among panelists andwere related to the difference in perfume level (0.8% vs. 0.9%).Further, it is believed that the base perfume would be habituating, evenat a lower perfume level if the test subjects used the product for alonger duration. The addition of nitrogen PRM's (non-sulfur-based)consistently showed greater resistance to habituation as compared to thecontrol, regardless of perfume level tested.
